    Here’s what the Space Development Agency wants from its first 10 satellites

    Nathan Strout The Space Development Agency is seeking proposals for its first batch of satellites, which will make up its initial transport layer — an on-orbit mesh network that will connect space-based sensors with terrestrial shooters. According to the May 1 solicitation, SDA is looking to award two contracts to build a total of 20 small satellites, which will comprise Tranche 0 of the National Security Space Architecture, a proliferated, low-Earth orbit constellation that will fulfill a multitude of military needs, including tracking hypersonic weapons; providing alternative position, navigation and timing data; delivering beyond-line-of-sight targeting; and more. Ultimately, the agency envisions a constellation made up of hundreds of interconnected satellites. Ten of those Tranche 0 satellites will form the agency's initial transport layer. The spiral development approach The agency is taking a spiral development approach to its National Security Space Architecture. Tranche 0 will be a testing and training segment that will demonstrate the integration of the architecture with other war-fighting efforts and inform future SDA developments. Tranche 0 is anticipated to be on orbit in the fourth quarter of fiscal 2022, with the SDA adding new tranches of satellites every two years, increasing the constellation's size and capabilities. Launch services will be acquired through the Orbital Services Program 4 contract or follow-on contracts. The philosophy behind the spiral approach is that the two-year cycles allow the agency to rapidly put new capabilities on orbit in response to evolving threats. Instead of waiting years for the perfect satellite system, the agency wants to push technologies that are currently ready into orbit as soon as possible, giving war fighters increased capabilities in the near term. With Tranche 0, the SDA wants to achieve periodic, regional, low-latency data connectivity. With Tranche 1, which will add 150 satellites to the constellation, the agency plans to provide persistent regional connectivity. Building a mesh network The National Security Space Architecture will be made up of several layers serving different functions. Tranche 0 will establish the transport layer, a space-based mesh network that will be able to pass data from one satellite to the next. The mesh network will operate as part of the Integrated Broadcast System, the Defense Department's standard network for transmitting tactical and strategic intelligence and targeting data. The key technology that will enable the transport layer are optical inter-satellite cross links, providing approximately 1 Gbps connections between the satellites. Each Transport Layer satellite will have four such cross links — forward, behind, right and left — which will allow them to pass data on to the nearest or next-nearest transport layer satellite operating in the same orbital plane. The satellites will also be capable of cross-plane cross links, meaning they will be able to connect to non-transport layer satellites operating above or below them. Assuming that they also have optical inter-satellite cross links, these non-transport layer satellites would then be able to pass data through the transport layer's mesh network to another satellite or even to a terrestrial shooter. For example, it could work like this: A space-based sensor collects imagery that it wants to pass to a ground-based system, but it is not within range of any ground station. No problem. The sensor would pass on that imagery to a transport layer satellite via an cross-plane optical cross link. The data would then bounce from transport layer satellite to transport layer satellite until it arrives above its destination, where it would then be downlinked to an optical ground terminal or distributed to the appropriate weapons system via the Link 16 tactical data network. In theory, this would allow shooters to receive space-based sensor data in near-real time. Since the SDA plans to continue building on the transport layer in subsequent tranches across multiple vendors, the optical inter-satellite cross links will need to be designed with interoperability in mind. The SDA also wants radio frequency cross links as a backup to the optical cross links. Tranche 0 will include 10 transport layer satellites — three of which will include Link 16 payloads. During an April industry day, SDA Director Derek Tournear said this initial, space-based mesh network will form the space network component to the Defense Department's Joint All-Domain Command and Control enterprise, or JADC2. “The transport layer, which is what the draft [request for proposals] and the industry day was talking about today, is going to be the unifying effort across the department. That is going to be what we use for low-latency [communications] to be able to pull these networks together, and that, in essence, is going to be the main unifying truss for the JADC2 and that effort moving forward. That is going to be the space network that is utilized for that,” Tournear explained. The agency has six goals for its Tranche 0 transport layer: Demonstrate low-latency data transport to the war fighter over the optical cross link mesh network. Demonstrate the ability to deliver data from an external, space-based sensor to the war fighter via the transport layer. Demonstrate a limited battle management C3 functionality. Transfer Integrated Broadcast System data across the mesh network to the war fighter. Store, relay and transmit Link 16 data over the network in near real time. Operate a common timing reference independent of GPS. According to the request for proposals, the SDA plans to award a contract Aug 10, with delivery expected by July 31, 2022. Responses to the solicitation are due June 1. https://www.c4isrnet.com/battlefield-tech/space/2020/05/05/heres-what-the-space-development-agency-wants-from-its-first-10-satellites/

  • Shipbuilding suppliers need more than market forces to stay afloat

    Shipbuilding suppliers need more than market forces to stay afloat

    By: Bryan Clark and Timothy A. Walton The U.S. Navy's award this month of the contract for its new class of frigates starts the very necessary process of rebalancing the U.S. surface fleet, but the competition also highlighted the U.S. shipbuilding-industrial base's increasing fragility. If they lost, two of the four shipyards bidding on the frigate were at risk of either going out of business or joining the underemployed ranks of U.S. commercial shipbuilders. Due to specialization, only one or two yards construct each class of Navy combat ship with workforces, equipment, and infrastructure that would be expensive and difficult to adapt. A decision on any single ship class, as with the frigate, can shut down a shipyard and send its workers to the unemployment line. Specialization is also a problem when orders increase. The Navy's two submarine shipyards, General Dynamics Electric Boat and Huntington Ingalls Industries' Newport News division, shrank the time needed to build subs by 20 percent during the past decade while increasing production to two per year. The rising sophistication of Virginia-class submarines has now reversed this trend, however, and submarine builders' challenges are only increasing. They recently started a new contract to build up to 10 of the larger Block V Virginia submarines and are in negotiation with the Navy on a block-buy contract for the first two Columbia-class ballistic missile submarines. Supplier challenges abound U.S. shipbuilders may be fragile, but their suppliers are on life support. After decades of being whipsawed by changes to shipbuilding plans and budget uncertainty, a shrinking number of suppliers are able and willing to stay in business. The Navy's recent initiatives to improve supplier production capacity and resilience don't go far enough to address its rising dependence on sole-source suppliers, which now provide more than 75 percent of submarine parts. For example, when problems with Columbia missile tubes led the Navy to seek new suppliers, it replaced the existing, sole source — BWXT — with another — General Dynamics — that will assemble tubes at the same facilities that are constructing parts for the Virginia and Columbia submarines. Last year, the Trump administration used the Defense Production Act to establish new suppliers for military missile fuel. The Navy should build on this effort to identify sole-source items for which an additional supplier is appropriate. In selecting additional suppliers, the Navy should prioritize attributes other than cost. Sole-source items by definition are important enough to justify seeking out or creating a single supplier rather than adapting the ship's design to use an existing item. Therefore, the Navy should emphasize the provider's track record in conducting similar or other challenging engineering; its ability to adjust to what will likely be variable demand and changing specifications; and the likelihood of quality production that avoids rework. Planning for resiliency The Department of Defense could help address the shipbuilding-industrial base's fragility with its current study of the number and mix of ships needed in the future fleet. Although the primary goal of this analysis should be determining the most effective fleet possible within likely budget constraints, it must also ensure the industrial base can build and sustain the future Navy. Industrial base considerations are not new to Navy force structure planning. During the last decade, the Navy or Congress added amphibious ships, submarines, destroyers and auxiliary vessels to maintain hot production lines or keep a shipyard afloat until the next order. Each of the Navy's new combatant ships are expected to cost more than $1 billion to build, constraining the Navy's ability to spread ship construction to other qualified shipyards to fill production gaps or extend classes to keep a shipyard in operation. The Navy could better support shipbuilders by rebalancing its fleet architecture to increase the number of smaller vessels such as corvettes or tank landing ships, and reduce the number of larger destroyers and amphibious warships. Smaller, less-expensive ships could be built in larger numbers per year, providing more flexibility in shipbuilding plans to stabilize the workload for shipbuilders and providing more scalability to align shipbuilding expenditures with changing budgets. Smaller ships could also be built at a wider range of shipyards, including those that only build commercial vessels and noncombatant government ships like Coast Guard cutters and oceanographic research vessels. These “dual-use” shipbuilders suffer today from a lack of coordination between commercial and government shipbuilding, which creates a feast-or-famine cycle of orders. The Navy and nation depend on a healthy shipbuilding-industrial base. To foster the industrial base in the face of natural and man-made challenges, the Navy should change its fleet design and shipbuilding plans, while investing to establish and qualify new suppliers. Without deliberate action, the U.S. shipbuilding industry will become increasingly fragile, limiting the Navy's ability to build the ships it needs and respond when today's competitions turn to conflict.

Walton is a fellow. https://www.defensenews.com/opinion/commentary/2020/05/20/shipbuilding-suppliers-need-more-than-market-forces-to-stay-afloat/
